New 485 transceiver

[tracyu]

Here's an interesting idea for RS485 networking. It's a transceiver you can cross wire and still have your system function.

Did you miss this:

Sympol is NOT interoperable with RS-422 or RS-485; that is, designers may not mix Sympol nodes with existing RS-485 nodes.

I'ts not RS485. It works by active and passive bus lines, a bit like can-bus, but in this case both positive and negative levels are considered active. I'ts not compatible with DMX/RDM.

You will have to be able to recognize bad data as the result of crossed wires but these http://focus.ti.com/docs/prod/folder...65hvd1794.html will let you swap wires on chip.
